What is a Dacia 1310 I airbag control unit?
The Dacia 1310 I airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It continuously monitors sensors and stores relevant crash data, ensuring the proper functioning of all airbag modules and seatbelt pretensioners in the vehicle to maximize occupant safety.
This electronic control unit is responsible for the instantaneous deployment of the airbags and seatbelt pretensioners within milliseconds. It is a safety-critical component designed to last the life of the vehicle.
The control unit communicates via the OBD interface, allowing error codes and status data to be read. It processes signals from acceleration and impact sensors.
Why is the Dacia 1310 I airbag control unit defective?
A Dacia 1310 I airbag control unit often fails because it stores crash data after an accident, preventing the system from restarting, or it suffers from internal communication failures and signal processing malfunctions that activate the airbag warning light. Such defects require specialized repair to restore full functionality of the safety system.
Crash data stored in the control unit can prevent the memory from being erased, rendering the system inactive. This is a common reason why an airbag control unit repair is necessary.
Communication failures or internal control unit malfunctions can cause the system to no longer interact properly with other vehicle components. Faulty signal processing in the control unit can also cause a persistent airbag warning light, even if no sensors are defective.
Common error codes for Dacia 1310 I airbag control unit repair
No publicly confirmed, exact OEM error codes are available for the Dacia 1310 I airbag control unit, but typical airbag control unit-specific errors such as communication failures (B1000, U1726) or implausible crash signals (17931/460B) can be identified as a starting point for diagnostics during repair. These codes directly indicate problems with the airbag ECU.
- B1000 → Control unit communication error → A fault in the data connection between the airbag control unit and other systems in the Dacia 1310 I.
- 17931 / 460B → Crash signal implausible signal in the control unit → The airbag control unit has processed an inconsistent or implausible crash signal, often after an impact.
- U1726 → No communication with airbag control unit → The vehicle system cannot establish a connection with the airbag control unit, which indicates a failure.
These error codes are general in nature, as no model-specific, verified list exists for the Dacia 1310 I. A precise diagnosis often requires specialized Dacia workshop tools.
Error codes that affect sensors, belt tensioners or seat occupancy are explicitly excluded here, as the focus is on control unit-specific errors that could make a repair of the Dacia 1310 I airbag control unit necessary.
What part numbers are available for the Dacia 1310 I airbag control unit repair?
At this time, no 100% verified exact OEM part numbers for the airbag control unit of the Dacia 1310 I are publicly available from preferred, trusted sources. This is because the Dacia 1310 I is an older model and corresponding parts may no longer be listed in a standardized manner, making it difficult to find a suitable part number for a repair.
Neither Bosch, Continental, Siemens, Autoliv, nor official manufacturer catalogs list exact OEM part numbers for this specific model. Even professional databases like TecDoc/TecAlliance do not offer confirmed original part numbers.
For a Dacia 1310 I airbag control unit repair or replacement, we recommend contacting an official Dacia service partner or Renault dealer. They may have access to archived data.
Alternatively, specialized repair providers who focus on airbag control units in older vehicles can often help. They offer repair services even if the exact OEM number is unknown.
